Raven and Raven treated E. perplexum Kirk, accepted by Allan (1961) as a distinct sp., as a synonym of E. chlorifolium. They also noted that some plants treated by Allan as E. chlorifolium var. kaikourense Cockayne are referable to E. chlorifolium, whereas they treated var. kaikourense sens. strict. as a synonym of E. wilsonii Cheeseman.
